Aristotle never intended for his Metaphysics to be read as a single, coherent book, yet it became the most influential philosophical text in Western history. The work is not a polished treatise but a collection of lecture notes, drafts, and fragments compiled by later editors, likely Andronicus of Rhodes, in the first century BC. Scholars describe the text as a farrago, a hotch-potch of ideas that jump between topics without clear transitions, leading some to believe it was never meant to be a unified whole. The title itself is a historical accident; Aristotle never called it Metaphysics, which means 'after the physics.' The name simply reflected the order in which his works were arranged in the library, placing these abstract writings after his works on natural science. Aristotle referred to the subject as First Philosophy, a study of being qua being, or existence as existence, rather than the existence of specific things like plants or stars. The text is organized into books labeled with Greek letters, from Alpha to Nu, but the order of composition remains unknown, and the current arrangement is the result of editorial decisions made centuries after Aristotle's death. This chaotic structure has led to centuries of debate, with some scholars arguing that the books form a continuous argument while others insist they are disparate essays stitched together by necessity.
The Nature of Wisdom
The opening of Book Alpha, or Book I, establishes a radical distinction between knowledge gained through the senses and wisdom gained through understanding causes. Aristotle argues that while the senses provide immediate data, true wisdom, or sophia, requires knowledge of the first principles, or arche, that explain why things are the way they are. He contrasts the wise man, who understands the why of things and can teach others, with the unwise, who only know that things are a certain way based on memory and sensation. This distinction allows the wise to command rather than obey, elevating the philosopher to a position of authority. The book surveys the history of philosophy, beginning with the material monists of the Ionian school and moving through to Plato, critiquing their attempts to explain the universe. Aristotle dismisses the idea that matter alone can be substance, arguing that if one strips away all properties, what remains has no properties at all and cannot be substance. He also rejects the notion that substance is the universal or the genus, criticizing the Platonic theory of Ideas as leading to absurdities. The core of his argument is that substance is a cause, a principle that explains change and existence, rather than a static object.The Core of Being
Books Zeta, Eta, and Theta form the heart of the Metaphysics, focusing on the nature of substance, or ousia, and the relationship between potentiality and actuality. Book Zeta begins by stating that being has several senses, and the purpose of philosophy is to understand the primary kind of being, which is substance. Aristotle considers four candidates for substance: the essence of a thing, the universal, the genus, and the material substrate, ultimately concluding that substance is a cause. He argues that essence is the criterion of substantiality, meaning that what a thing is by its very nature is what defines it. For example, a human is a human by nature, but being musical is not part of one's essential nature. Book Eta summarizes these arguments, adding details about difference and unity, while Book Theta defines potentiality and actuality. Potentiality is the principle of change in another thing or in the thing itself, while actuality is the completed state of something that had the potential to be completed. This relationship is distinct from the relationship between form and matter, as it occurs over time, or diachronically, rather than at fixed points in time, or synchronically. The distinction allows Aristotle to explain how things change and develop, moving from a state of potential to a state of actuality.
